The application provides a display screen.

As shown in fig. 3 to 6, in the embodiment of the present application, the display screen includes an array substrate 1, a color filter substrate 2, and a driving chip 3. A non-display area 11 of the array substrate 1 is provided with a first TFT (Thin Film Transistor) unit 13 and a plurality of second TFT units 14, and each of the first TFT unit 13 and the second TFT units 14 has a gate (not shown) of a photosensitive material; the color film substrate 2 is provided with a first shading material layer 21 corresponding to the first TFT unit 13, and the color film substrate 2 is provided with a color transparent film material layer 22 corresponding to the plurality of second TFT units 14; the driving chip 3 is electrically connected to the first TFT unit 13 and the second TFT unit 14.

In practical application, the display screen disclosed by the application can be used in combination with an existing intelligent terminal such as a mobile phone, and specifically, the first TFT unit 13 is covered by the first light-shielding material layer 21, and the gate of the photosensitive material of the first TFT unit 13 cannot feel the ambient light intensity and the color temperature, so that the value of the first current Ids (hereinafter referred to as Ids 1) passing through the source and the drain of the first TFT unit 13 is not changed; the ambient light can penetrate through the color transparent film material layer 22 and irradiate the second TFT unit 14, and the light with different colors transmitted from the color transparent film material layer 22 irradiates the gate of the photosensitive material of the second TFT unit 14, so that the intensity and the color temperature of the ambient light received by the gate of the photosensitive material are different, and thus the second current Ids passing through the sources and the drains of the second TFT units 14 are different. The driving chip 3 compares the plurality of second current Ids values with the first current Ids values to obtain a plurality of sets of current ratios, and then calculates the luminance information of the ambient light passing through the color transparent film material layer 22 according to the current ratios, so that noise (for example, stray light) interference can be shielded, and the TFT photosensitive accuracy can be improved. The driving chip 3 calculates the color temperature and color coordinates of the ambient light according to the brightness information and feeds the color temperature and color coordinates back to the intelligent terminal for adjusting the color temperature. This application utilizes the photosensitive material grid among the TFT to receive ambient light, see through behind the colored printing opacity membrane according to ambient light and produce different electric currents and generate the current ratio in a plurality of TFT units, calculate according to the current ratio and obtain the ambient light colour temperature, thereby adjust the colour temperature that is provided with the intelligent terminal of this display screen, need not install the colour temperature sensor at the display screen, the manufacture craft has been simplified, reduce manufacturing cost, the work electric energy that provides for the colour temperature sensor has been saved, thereby the consumption at intelligent terminal has been reduced. When the TFT unit and the material layers are disposed in the non-display area 11 of the array substrate 1, the area ratio of the first light-shielding material layer 21 is small, the screen ratio of the display area 12 of the array substrate 1 is increased, and the full-screen visual effect of the display screen is increased. When the intelligent terminal is applied to intelligent terminals such as mobile phones, grooves do not need to be formed in the shell structure of the intelligent terminal, the overall structural strength and the integrity of the intelligent terminal can be effectively improved, and the manufacturing process is simplified.

In practical applications, the first light-shielding material layer 21 may be completely stacked and covered on the TFT unit, and then the area of the surface of the first light-shielding material layer 21 corresponding to the second TFT unit 14 is opened to coat the color light-transmitting film material layer 22.

In the technical solution of the present application, the surface of the color light-transmitting film material layer 22 has three color bands 221, three the color bands 221 are red, green and blue respectively. Of course, there are three second TFT units 14.

The ambient light can penetrate through the color transparent film material layer 22 to irradiate the second TFT units 14, and the three second TFT units 14 correspond to the red, green and blue color bands 221 one by one, so that the passing current values can be represented as ids2, ids3 and ids4. The driving chip 3 obtains a plurality of groups of current ratios by comparing a plurality of second current Ids values with the first current Ids values, namely Ids2/Ids1, ids3/Ids1 and Ids4/Ids1, and then calculates the brightness information of the ambient light penetrating through the color light-transmitting film material layer 22 by using the current ratios, so that noise (such as stray light) interference can be shielded, and the photosensitive precision of the TFT is improved. The color transparent film material layer 22 having red, green and blue bands 221, i.e. a color filter (color filter), referred to as RGB filter for short, utilizes the three-primary color mixing principle to mix the three colors of light in nature into a mixture of three colors of RGB in different proportions. When the method is applied to the application, the ambient light with different color temperatures can be transmitted to form red, green and blue colors, so that the photosensitive material grid of the TFT unit can receive the current ids with different values generated on the source electrode and the drain electrode of different TFT units, and the current ids can be used for calculating the current ratio.

In practical applications, the non-display region 11 of the array substrate 1 may further include a third TFT unit (not shown) and a plurality of fourth TFT units (not shown), and similarly, the third TFT unit is covered by the first light shielding material layer 21, the fourth TFT unit is covered by the color transparent film material layer 22, that is, the using method and the operation principle are the same as those of the first TFT unit 13 and the second TFT unit 14, and the number of the fourth TFT units is the same as that of the second TFT unit 14. When the driving chip 3 works, the third TFT unit passes through a third current Ids value (hereinafter abbreviated as Ids 8), and a fourth current value passed by the fourth TFT unit can be represented as Ids5, ids6 and Ids7, so that the driving chip 3 can simultaneously obtain Ids2/Ids1, ids3/Ids1, ids4/Ids1, ids5/Ids8, ids6/Ids8 and Ids7/Ids8, interference resistance is further increased, and photosensitive accuracy of the TFT is improved. In practical application, two groups of TFT units with the same structure can be respectively close to the left side and the right side of the display screen so as to increase the ambient light receiving angle and avoid mutual interference between the two same structures.

In order to improve the accuracy of color temperature calculation, in the technical solution of the present application, the widths of the three color bands 221 are the same.
